A calculator is a great tool for solving ACT math problems more quickly than you can either in your head or using a pencil and scratch paper. At the same time, however, you want to avoid overusing it for[more…]

When choosing a calculator for the ACT, remember that while some are allowed others are not. Your safest choices include basic, scientific, and graphing calculators; conversely, you need to avoid laptops[more…]

If you have just purchased a calculator for the ACT, you should use it for at least one practice test so you can get the feel of where the important function keys are. For example, if you have a fancy[more…]

A word problem (also called a story problem or a problem in a setting) gives you information in words rather than in just equations and numbers. To answer an ACT word problem, you have to translate the[more…]

Using your calculator to find a result on the ACT is straightforward when you know the number you’re calculating with and the percentage you’re taking. However, some math questions on the ACT will involve[more…]

Many students find math questions that involve percent increase and percent decrease somewhat confusing. The first step to answering these questions correctly on the ACT is identifying them when they’re[more…]

Some math questions on the ACT will involve ratios and proportions. Both ratio and proportion problems involve comparing quantities, and they require that you know how to work with fractions and how to[more…]

Algebra is chock-full of words that are useful but often misunderstood. To do well on the ACT Math test, you should be able to define these important terms: variable, constant, equation, expression, term[more…]

Some equations on the ACT Math test may include one or more extra variables. Generally speaking, when an equation has more than one variable, you can’t solve it. As a result, in most cases, you must solve[more…]

As when solving an ACT Math problem that includes an expression with absolute value, you also need to split an inequality with absolute value into two separate inequalities. However, keep in mind one twist[more…]

Solving word problems is one of the most common reasons to use a system of equations. For example, some word problems in the ACT Math test that would be difficult to approach using a single variable are[more…]

The ACT will probably include some math problems that involve direct proportionality. Direct proportionality refers to a connection between two variables based on either multiplication or division, where[more…]
